基于非参数检验对运动员反应时间的相关性分析

Correlation Analysis of Athlete’s Reaction Time Based on Non-parametric Test

短距离比赛中,运动员的起跑反应与比赛成绩紧密关联.针对关联分析,通过构建Kendall相关模型计算运动员比赛成绩和反应时间的相关系数,结果显示运动员的比赛成绩与相应的起跑反应时间有着显著的低相关关系.针对差异分析,首先构建Mann-Whitney U检验对运动员反应时间在性别上的差异进行分析,而针对运动员的反应时间在比赛年份、项目、比赛的不同阶段的差异性,通过构建多独立样本的Kruskal-Wallis检验进行分析,最终结果显示运动员的反应时间在性别、比赛年份、比赛项目、比赛的不同阶段中皆具有显著的差异性.

In short-distance competitions, the starting reaction of athletes is closely related to the competition results. For the correlation analysis, the correlation coefficient between athletes’ competition performance and reaction time was calculated by constructing a Kendall correlation model. The results showed that the athlete’s competition performance had a significant low correlation with the corresponding starting reaction time. For the analysis of differences, the Mann-Whitney U test is first constructed to analyze the differences in the reaction time of athletes by gender, and for the differences in the reaction time of athletes in different stages of the competition year, event, and competition, a Kruskal with multiple independent samples is constructed. Through Kruskal-Wallis test analysis, the final result shows that athletes’ reaction time has significant differences in gender, competition year, competition event, and different stages of competition.
